After a bout of trouble with 10.04, 10.10 fixed the driver issues with my Intel video card. I avoided upgrading for some time, but bit the bullet this weekend. I was able to upgrade and get the box running easily, but when I came back to the office and the docking station I ran into trouble.

I have a second monitor and it is being displayed in mirror mode. The resolution is that of the laptop (so 1/2 of the real-estate is lost). Unfortunately, I am not sure HOW the video card decided to even display to the second monitor. xrandr does not even see it.

So,
Dell E6510 on docking station trying to drive a Dell u2211h with a DVI connector.
Displays does not see second display and the "Detect Display" button gives no feedback.
